Abstract
A high-voltage synthesis suspension type insulator comprises a fitting seat, a fitting pull rod and a porcelain dish which is connected with the fitting seat and the fitting pull rod through an adhesive layer. The insulator is characterized in that an outer side surface of the porcelain dish is provided with a silicon rubber sheath which wraps the porcelain dish and is extended so as to form at least one airfoil-shape skirt edge; a bottom edge of the silicon rubber sheath is provided with at least more than two annular skirt edges. According to the insulator of the utility model, the silicone rubber sheath is extended on an outer surface of the porcelain dish so that the airfoil-shape skirt edge is formed and a transmission line creepage distance is increased. The insulator is suitable for safety usage of 1000kv power supply and power transformation line and simultaneously weight is mitigated. In a same pulling force condition scope, compared to a porcelain dish insulator or a composite dish insulator, by using the insulator of the utility model, 10-25% of suspension quantities are increased. If a substation voltage of the line is increased, only the quantities of the annular skirt edges need to be increased so that the insulator is suitable for the increase of the voltage. Therefore, the high-voltage synthesis suspension type insulator introduced in the utility model possesses a great significance for power supply and power transformation transmission.
Description
Technical field
The utility model relates to a kind of high suspension insulator that is pressed into, and is specially adapted to high pressure in power transformation circuit.
Background technology
In the last few years, along with the rise of diversification building, indispensable high-tension line in architectural design was had higher requirement, thereby made the suspension insulator of insulation and fixing cord effect obtain applying more and more widely.Now widely used suspension insulator, is porcelain insulating disc and gold utensil and forms, and its antifouling ability is lower, especially can not use in higher power transmission and transformation voltage circuit, if voltage raises, due to himself fault of construction, exists the danger of fracture.
Summary of the invention
The utility model has overcome the deficiency of above-mentioned prior art, on existing insulator basis, makes improvements, and its object is to provide a kind of high suspension insulator that is pressed into.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions.
A kind of high suspension insulator that is pressed into, comprise gold utensil seat, gold utensil pull bar, and the porcelain dish linking together by adhesive phase and gold utensil seat and gold utensil pull bar, it is characterized in that the outer surface of described porcelain dish is provided with a parcel porcelain dish and extends the silicone rubber jacket with an above aerofoil profile shirt rim.Described silicone rubber jacket base is provided with plural annular shirt rim.
The beneficial effects of the utility model are: the extension by silicone rubber jacket at porcelain dish outer surface, and form aerofoil profile shirt rim, increased transmission line creepage distance, can be applicable to the safe handling for power transformation circuit up to 1000kv, alleviated weight simultaneously, in identical pulling force condition and range, than the suspension quantity of the porcelain disc insulator using in the past or the capable insulator increase of compound dish 10-25%.If circuit increases for power transformation voltage, as long as suitably increase the quantity of annular shirt rim, just can be suitable for the increase of voltage, so the height introduced of the utility model is pressed into suspension insulator and says for supplying power transformation to transport, be significant.

Embodiment
Below in conjunction with accompanying drawing, introduce in detail the utility model specific embodiment.
As shown in Figure 1, the utility model comprises gold utensil seat 1, gold utensil pull bar 2, and the porcelain dish 3 linking together by adhesive phase 4 and gold utensil seat 1 and gold utensil pull bar 2, the outer surface of described porcelain dish 3 is provided with a parcel porcelain dish 3 and extends the silicone rubber jacket 6 at least with an aerofoil profile shirt rim 9.Described sheath 6 all seals it at the upper surface of porcelain dish 3, and extend to gold utensil seat 1 below.In order to increase creepage distance, on the base of described silicone rubber jacket 6, be at least provided with plural annular shirt rim 7.Like this, not increasing under the prerequisite of this insulator outward appearance and installation volume, greatly increased creepage distance, therefore can adapt to up to 1000kv for power transformation circuit.In use, gold utensil pull bar 2 is inserted in gold utensil seat 1, then locking pin 6 is inserted in pin-and-hole, complete installation.
